| 摘 要： | 实验表明，非晶态合金在激波影响下会转变为纳米晶.最近的实验进一步发现，Fe73.5Cu1Nb3B9Si13.5非晶态合金中的Cu,Nb在激波晶化中的细化作用被抑制，且样品在这种转变之后作进一步的退火处理，其晶粒度变大而晶格常数变小.在激波晶化机理分析中提出了“激波流体晶化”构想.

| Abstract: | Non-crystalline alloys can be turned into nano-crystalline under shock waves. This has been proved by our experiments.Recently,we have discovered that the functions of Cu and Nb of Fe73.5Cu1Nb3B9Si13.5 in shock wave crystallization are restrained, and the size of crystallites in the crystallized alloy Fe73.5Cu1Nb3B9Si13.5 is increased and its lattice constant is decreased after the sample is annealed again. These phenomena are worth to study further. The model of fluid-change for explaining the law of shock wave crystallization is suggested in this paper. |
